German Apple Strudel With Vanilla Sauce

German apple strudel with vanilla sauce is the ultimate cozy dessert. The warm, spiced apples and flaky pastry taste even better when paired with a smooth, creamy vanilla sauce poured over the top.

Vanilla sauce, known as Vanillesoße in Germany, is a classic partner for Apfelstrudel. It is silky, lightly sweet, and coats every bite with a rich vanilla flavor.

This recipe uses store-bought puff pastry to keep things simple. The vanilla sauce comes together on the stove in just a few minutes. Together, they make a dessert that feels fancy but is easy enough for any home baker.

Instructions

For the Strudel

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
2. In a large bowl, mix the sliced apples, sugar, cinnamon, and salt. Add raisins if using.
3. Toast the breadcrumbs in a dry pan over medium heat for 2 minutes until light golden. Set aside.
4. Lay the puff pastry flat on the parchment paper. Sprinkle the toasted breadcrumbs over the pastry, leaving a 1-inch border.
5. Spoon the apple filling along one long side of the pastry. Do not overfill.
6. Roll the pastry over the filling from the filled side. Tuck in the ends and press the seams with a fork.
7. Brush the top with melted butter, then brush with beaten egg for a shiny finish.
8. Cut 3 to 4 small slits on top to let steam escape.
9. Bake for 30 to 35 minutes until the pastry is golden brown and puffy.
10. Cool for 10 minutes before slicing.

For the Vanilla Sauce

1. In a small bowl, whisk the egg yolks, 1/4 cup sugar, and cornstarch until smooth.
2. In a medium saucepan, heat the milk and heavy cream over medium heat until warm. Do not boil.
3. Slowly pour a little of the warm milk into the egg mixture, whisking constantly. This warms the eggs gently.
4. Pour the egg mixture back into the saucepan with the rest of the milk.
5. Cook over low heat, stirring constantly, for 5 to 7 minutes until the sauce thickens. Do not let it boil.
6. Remove from heat. Stir in the vanilla extract and butter until smooth.
7. Pour the sauce into a bowl and cover with plastic wrap touching the surface. This stops a skin from forming.

To Serve

1. Slice the warm strudel into pieces.
2. Dust with powdered sugar.
3. Pour warm vanilla sauce over each slice and serve.

Tips for the Best Apple Strudel and Vanilla Sauce

• Keep the sauce moving. Stir constantly while cooking so the eggs do not scramble.
• Do not boil the sauce. High heat can curdle the eggs. Low and slow is best.
• Use fresh vanilla. Vanilla extract or a scraped vanilla bean gives the best flavor.
• Toast the breadcrumbs. This keeps the bottom of the strudel crisp, not soggy.
• Slice apples thin. Thin slices cook evenly and soften inside the pastry.
• Seal the edges well. Press firmly with a fork so the filling stays inside.

Troubleshooting

• Sauce too thin? Cook it a little longer on low heat, stirring constantly.
• Sauce lumpy? Whisk faster and strain the sauce through a fine mesh sieve.
• Sauce too thick? Stir in a splash of warm milk until smooth.
• Soggy strudel? Add extra breadcrumbs and bake on the lower rack for 5 more minutes.

Variations

• Vanilla bean sauce: Use a real vanilla bean instead of extract for a richer flavor.
• Rum raisin strudel: Soak the raisins in rum before adding them to the filling.
• Walnut strudel: Add 1/2 cup chopped walnuts to the apple mix.
• Caramel vanilla sauce: Stir 1 tablespoon caramel sauce into the vanilla sauce before serving.
• Vegan vanilla sauce: Use oat milk, coconut cream, and cornstarch instead of eggs and dairy.

Storage and Reheating

To store the strudel: Keep leftovers in an airtight container in the fridge for up to 3 days. At room temperature, it stays fresh for 1 day.

To store the vanilla sauce: Keep it in a sealed container in the fridge for up to 3 days. Press plastic wrap onto the surface to stop a skin from forming.

To reheat the strudel: Warm in a 350°F (175°C) oven for 8 to 10 minutes. This keeps the pastry flaky.

To reheat the sauce: Warm gently on the stove over low heat, stirring often. Add a splash of milk if it thickens too much.

To freeze: Wrap the baked strudel tightly in plastic wrap and foil. Freeze for up to 2 months. The vanilla sauce does not freeze well, so make it fresh.
